Sean (R) and Elizabeth Canning are sworn in during a hearing in a lawsuit their daughter Rachel Canning filed against them in Morristown March 4, 2014. The New Jersey student who says her parents abandoned her when she turned 18 lost a first round on Tuesday in the lawsuit she filed against them for school costs and living expenses, a case that could set a precedent for a family’s obligation to support a child who has left home. A family court judge denied a request by Canning of Lincoln Park, New Jersey. (Landov)
